BATTERY PACK THERMAL MANAGEMENT SYSTEM AND THERMAL MANAGEMENT SYSTEM FOR ELECTRIC VEHICLE

摘要

A battery pack thermal management system and a thermal management system for an electric vehicle. The battery pack thermal management system (1) comprises: a battery pack thermal management device (11), a processor (12), and a solenoid valve network (13) connected to the battery pack thermal management device (11), where an external port of the solenoid valve network (13) is connected to an external cooling system (2); the processor (12) is used for controlling the work status of solenoid valves in the solenoid valve network (13), thus allowing the battery pack thermal management device (11) to utilize the heat generated by the external cooling system (2) to heat a battery pack. The solution increases energy utilization rate.
